To clarify, the font problem is that when running as an AppImage, the fonts
do not look the same as when the same application runs in the same
distribution for the same user when that application is installed with pip.
In other words, the pip installed version looks great, but the AppImage one
can look awful and very much out of place. Here is a composite image (43
kB) that illustrates the problem on two different distros:
The image illustrates that with the first distro, the AppImage font changes
to a serif font, which is wrong.
With respect to Simon's point about the legality of font aliasing, it's
entirely possible I'm using the wrong terminology for what I thought was
aliasing. Perhaps the correct term is hinting? In any case, as can be seen
in the second pair of images, the hinting / aliasing is different in the
AppImage. I suspect the first pair of images also have the same hinting /
Although the distributions are different (Fedora and Ubuntu derived
respectively), that's not the determining factor, as an AppImage in Kubuntu
looks like it does in the Korora install.
